This technique is especially useful when both the vitreous and retina are difficult to access because of media opacity, a small pupil, or a microcornea. In this context, the anterior vitreous is often difficult to dissect because of its complex pathological changes. This article reviews the common anatomical features and pathologies that are observed in the anterior vitreous, as well as the applications and indications of endoscopy-assisted vitrectomy in the anterior vitreous.展开更多

Ciliary bodies were evaluated using ultrasound biomicroscopy pre-operatively and direct visualisation intraoperatively. All selected individuals(seven patients/seven eyes) underwent EAV. Removal of ciliary membrane and traction, gas/silicone oil tamponade(GT/SOT), and scleral buckling(SB) were performed in selected eyes. Outcome measurements mainly included intraocular pressure(IOP) and best-corrected visual acuity(BCVA).·RESULTS: Seven eyes from 7 male aphakic patients with a mean age of 45(range, 20-68)y were included in this study;the average follow-up time was 12(9-15)mo. GT was performed in 2 eyes;membrane peeling(MP) and SOT in 2 eyes;and MP, SOT, and SB in 3 eyes. The mean preand post-operative IOP were 4.5(range, 4.0±0.11 to 4.8±0.2) mm Hg and 9.9(range, 5.6±0.17 to 12.1±0.2) mm Hg at 52wk(12mo), respectively. BCVA improved in six eyes;one eye still showed light perception, and no bulbi phthisis was observed.·CONCLUSION: Endoscopy offers improved judgment and recognition and has an improved prognosis for chronic hypotony. Therefore, endoscopy can be an effective and promising operative technique for chronic traumatic hypotony management.展开更多
